Shinji Ikari was farting away as he ate cake and pie.

PPRPRRRRBBBTTTTTT

"Ohm, hm hm," he mumbled, mouth full of pie as he chewed. He swallowed. His fat cheeks oozed as he smiled. "Oh, I'm so tooty today, Kaworu-san!"

FRRRRRTTT

"It is a marvelous symphony, Shinji-kun," said Kaworu Nagisa. He reached back and stroked Shinji's colossal left buttock. "Your anus is a beautiful musical instrument."

Shinji smiled, and blushed, and kept eating.

They were in their usual bakery. Shinji's bariatric wheelchair had been pushed up to the table reserved for him, with the semicircular cutout that afforded him room for the ingress of his belly. He was hugely fat. He currently clocked in at 406 kilograms. He lounged in his massive seat, his enormous belly swollen tick-like in front of him, his enormous bottom bloating in a shelf behind him, each billowing cheek like a beanbag chair. Of course, most of the precise shape of his ass cheeks was hidden by the huge bariatric diaper he wore, as well as the white floral print muumuu he wore over that. Shinji wore nothing these days but huge dresses. Nothing else would fit his elephantine form.

Prrrrrrbbbbbbttttttt

Shinji farted again as he plowed through a coconut cream pie. There were all manner of cakes and pies at his table, in various stages of eating. The swollen fat boy was grazing at the moment, taking bites here and there from different pies and cakes rather than concentrating on devouring any one in particular. He was in heaven. He had a marvelous sugar rush going on, enhanced by the huge glass of Vanilla Coke he was drinking. He was buzzing with good feelings and basked in delight. His vast body was billowing and huge. Also, from time to time, Kaworu would touch and stroke him, which only increased Shinji's good mood. He loved when his boyfriend touched him. It made him feel so special.

Frrrrrrbbbtttttt

It went without saying that all his farts stank. Shinji was a putrid farter: all his flatuence was extraordinarily stinky, a consequence of his terrible diet. A miasma of stench surrounded the gargantuan former Eva pilot, a stink that clung to his billowing fat bulk. Shinji was often stinky these days. If it wasn't his farts that stank, it was his poop, his free-flowing fecal incontinence that would empty massive loads of feces into his diapers where they would sit for hours as he and Kaworu ran errands and got Shinji things to eat. Shinji had gotten comfortable stinking. He was fully at ease smelling terrible. Indeed, he felt a certain pleasure at it. He was such a big, stinky boy, and nobody could stop him. And he knew Kaworu loved it, and whatever Kaworu loved, Shinji loved. Kaworu would often kiss Shinji deeply when he was farting up a storm. Shinji had grown to associate flatulence with his caretaker's affection.

PPPPPRRRRRTTTTTT

Besides, it wasn't like he could stop it, anyway. His loose, sloppy anus couldn't hold in gas these days, any more than it could hold in shit. Years of anal sex had turned Shinji's sphincter into a swinging gate. Everything that wanted to get out of his butthole did so with ease. And everything that wanted to go in, got in just as easily.

FRRRBBBBTTT

"Hmm hmm," said Shinji, hefty chins sloshing as he turned his head. "Kaworu-san, when we get home, do you think I could have one of our buttplugs inside me for a while?" He smiled, icing-covered lips curving in an expression of delight. "I do really think I need something to fill me up for a good chunk of time."

"Perhaps, Shinji-kun," said Kaworu. "When do you suspect you will have another bowel movement? Do you believe it might be soon?"

"Hmm," Shinji's fat face, so piglike, sagged and swelled as he made a thinking expression. "I don't think so, Kaworu-san. I took such a big poo poo right before we left the house. You remember, it was huge! I'm probably not going to go again for hours, even once we get home." He chuckled. "Though I know sometimes I do surprise myself on that!"

"Well, Shinji-kun, just so long as you don't believe you'll be pooping again soon. You know how troublesome it is, for you to poop out one of our plugs not long after having it put in."

"Yes, yes, I know," said Shinji, waving a plump hand his direction. "You do have to take some trouble to put them in me, I'd hate to crap it out so soon after." Shinji ran his hands down his massive belly and side rolls. "I've got a lot of body you have to handle these days!"

"All by design, my precious pet," said Kaworu. He leaned in, and kissed Shinji on the cheek. "My precious pet pig, you must keep eating."

Shinji made a soft noise in his throat, and forked another bite of cake into his mouth.
